In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.

This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

In this activity, learners will use string and salt to lift an ice cube out of a glass of water. Salt depresses the freezing point of water, allowing it to melt around the string and refreeze.

Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!

In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.

In this activity (on pages 4-5), learners make fake snow by adding water to the super-absorbant chemical from diapers, sodium polyacrylate.

In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.

Create gas with a glass of water, some wire, conductors and a battery! You will be separating water (H2O) into oxygen and hydrogen.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

This display shows the dangers of acid rain on buildings and other structures as two concrete bunny rabbits are disintegrated by sulfuric acid. Learners scrape chalk onto the concrete bunnies.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.
